Restore Peak Performance to Your Cadillac Escalade ESV
Is your 2015 or 2016 Cadillac Escalade ESV suffering from mysterious engine issues, poor fuel economy, or an illuminated Check Engine Light? The Engine Control Module (ECM), often called the vehicle’s main computer, is the central command for all critical engine functions. When it begins to fail, it can cause a cascade of frustrating and difficult-to-diagnose problems. This genuine GM Engine Control Module, part number 12676230, is the definitive solution to restore your vehicle’s factory performance, drivability, and reliability.
Unlike a generic part from a local store, this ECM arrives at your door pre-programmed to your vehicle’s specific Vehicle Identification Number (VIN). This critical step ensures seamless communication between the module and all other electronic systems in your Escalade. By flashing the unit with the latest GM-certified software updates, we eliminate the need for an expensive trip to the dealership for programming. This saves you both time and money, getting you back on the road faster.
Is Your 2015-2016 Escalade ESV ECM Failing?
A faulty ECM can manifest in numerous ways, often mimicking other component failures. If you’re experiencing any of the following, a failing engine computer could be the culprit.
- ✔ Check Engine Light: The most common indicator, often with codes related to sensors, emissions, or module communication.
- ✔ Engine Stalling or Misfiring: The engine may stall unexpectedly, run rough, or misfire as the ECM fails to properly manage spark and fuel.
- ✔ No-Start Condition: A completely failed ECM can prevent the engine from starting at all, as it controls the fuel injectors and ignition coils.
- ✔ Poor Fuel Economy: Incorrect air/fuel mixture calculations can lead to a sudden and significant drop in MPG.
- ✔ Transmission Shifting Issues: The ECM works closely with the Transmission Control Module (TCM), and a fault can cause harsh shifting or erratic gear changes.
- ✔ Intermittent Electrical Problems: Seemingly unrelated issues with gauges, lights, or accessories can sometimes be traced back to a failing main computer.

Frequently Asked Questions
Do I need to get this ECM programmed by a dealer?
No. We program the module to your vehicle’s specific VIN before we ship it. This means it’s ready for installation right out of the box, saving you a costly trip to the dealership.
Where is the ECM located on my 2015-2016 Escalade ESV?
On the 2015-2016 Escalade ESV, the ECM is typically located in the engine compartment on the left-hand (driver’s) side, near the front. It’s a silver metal box with several large electrical connectors.
How do I provide my VIN?
You can add your VIN to the notes section during checkout or send it to us in a message after you complete your purchase. We cannot ship the module until we have your VIN to program it.
Will this fix my check engine light?
If the check engine light is caused by a faulty ECM, then yes, this replacement part will resolve the issue. However, it’s crucial to properly diagnose the vehicle first, as the light could be on for many other reasons.
Is this a plug-and-play part?
Because it comes pre-programmed, it is very close to plug-and-play. After installation, some vehicles may require a simple security relearn procedure or a Crankshaft Variation (CASE) relearn, which can be performed with a compatible high-level scan tool.
